1991 Chevy Truck - compushift Control - Photo 11

One problem we had with the transmission prior to the rebuild was keeping track of what gear we were really in, and whether or not the torque converter was locking up due to soft shifts and failing solenoids. These two aspects of the transmission, plus greater diagnosis and adjustability, convinced us to try out B&M's offering of a Compushift controller. The Compushift is a stand-alone computer designed to run an electronic automatic transmission whether it is in a factory or custom vehicle, and it quickly installs under the driver's or passenger's seat for a safe, protected control location.
